Subject [jira] [Commented] (YARN-2500) [YARN-796] Miscellaneous changes in ResourceManager to support labels
Date Thu, 18 Sep 2014 09:28:34 GMT

    [ https://issues.apache.org/jira/browse/YARN-2500?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14138720#comment-14138720
] 

Wangda Tan commented on YARN-2500:
----------------------------------

Highlight major changes for easier review:
* Properly setup and check label expression according to ResourceRequest, ApplicationSubmissionContext
and queue default label expression
** Located in {{ApplicationMasterService}}, {{RMServerUtils#validateResourceRequest}}
* In the past, ResourceRequest of AM container created in two places (one in {{RMAppManager}},
another one in {{RMAppAttemptImpl}}), when trying to allocate resource from YarnScheduler,
the 2nd ResourceRequest doesn't normalized. Now reduced this to only one: ResourceRequest
will be created in {{RMAppManager}} only, and it will pass ResourceRequest to RMAppImpl to
allocate resource
* Check if a queue has permission to access all labels in label-expression of a ResourceRequest,
located in {{SchedulerUtils.validateResourceRequest}}
* Added getLabels() and getDefaultLabelExpression to Queue
* Added get/set NodeLabelManager in RMContext
